Cisco VG410 Voice Gateway provides VoIP connectivity to analog devices such as analog desk phones, analog conference room phones, fax machines, and modems. This voice gateway provides several improvements from the previous high-density analog and digital extension modules (EVMs) in the following ways:

• Software Digital Signal Processor (DSP): The Cisco VG410 Voice Gateway chassis utilizes its built-in CPU cores to handle the digital signal processing (DSP) tasks required for software implementation. This means that the functionality typically provided by a separate DSP component is now distributed among the CPU cores within the device. Further, the CPU cores effectively handle the necessary DSP operations. The software DSP comes pre-installed as part of the manufacturing process.

• FXS-E (extended loops or long loops) support: The first 24 ports of all the SKUs on the new modules support FXS-E with:

  • Higher loop current (35 mA) to accommodate specialty phones

  • Longer loop length for loops with 26 AWG wire, up to 11,000 feet (3400 meters)

  • Higher ringing voltage (65 Vrms, no load)

In addition to these features, Cisco VG410 Voice Gateway supports the following features:

• Webex calling

• Caller line ID

• G.711, G.729a, G.729ab, and G.726

• G722, iLBC

• Fax pass-through and relay (T.38)

• Modem pass-through, Modem relay, and V.150.1 MER modem relay support

• DTMF detection

• Echo cancellation

• Voice activity detection

• Comfort noise generation

• Real-Time Control Protocol (RTCP)

• Acoustic shock protection

• Real-Time Transport Protocol (RTP)

• RFC 4733 Digit Relay

• Noise reduction

• Call Details Records (CDR)

• Support for Loop-start and Ground start signaling

• Support for interworking with Cisco Unified Communications Manager (CUCM): Skinny Client Control Protocol (SCCP), Session Initiation Protocol (SIP), and Media Gateway Control Protocol (MGCP) 0.1

• Cable detection: GR909 line test

The following tables specify the Cisco VG410 Voice Gateway SKU information. All the SKUs support the following external interfaces:

Use the Cisco Product Identification (CPI) tool to find labels on the platform. The tool provides detailed illustrations and descriptions of where labels are located on Cisco products. It includes the following features:

• A search option that allows browsing for models by using a tree-structured product hierarchy.

• A search field on the final results page that makes it easier to look up multiple products.

• End-of-sale products clearly identified in results lists.

The tool streamlines the process of locating the serial number labels and identifying products. Serial number information expedites the entitlement process and is required to access support services.

The following image shows the location of the labels on the Cisco VG410 Voice Gateway.

The Serial number (SN), Common language equipment identifier (CLEI), Top Assembly Number (TAN), Product ID (PID), PID version ID (VID), and Quick response (QR) code are printed on a label at the bottom of the hardware or on a label tray located on the chassis.
